#### Rules for Using Standard Horizontal and Bridge CMMs

The following description contains rules you should follow to have manual scanning compensate correctly and with greater speed on standard Horizontal and Bridge types of CMMs.

Fixed Distance Scans, Fixed Time Scans, and Fixed Time / Distance Scans

- You must lock one axis of the CMM during the scan. PC-DMIS will take the scan in a plane perpendicular the locked axis.

- On each of these three types of scans, you must type the InitVec and DirVec values in the Machine Coordinate System . This is required because you are locking one of the machine axes.

Body Axis Scans

- You should not lock any axis during the scan. PC-DMIS will take the scan by crossing the probe over a keyed-in Body Axis location. Each time the probe crosses this given plane, the CMM takes a reading and passes it to PC-DMIS.

- On this type of scan, you need to type the InitVec and DirVec values in the Part Coordinate System. This is required so that the probe can traverse the body axis location indicated.

- Make sure you type the body axis in the Part Coordinate System.
